Biodegradable thermoplastic elastomers |
摘要 |
The present invention relates to a biodegradable thermoplastic elastomer having the general formula A-B-A wherein each A is an amorphous polymer having a glass transition temperature (Tg)>40° C. or a semi-crystalline polymer having a glass transition temperature (Tg) and/or melting temperature (Tm)>40° C.; B is a copolymer of -caprolactone (CL) and at least one additional monomer selected from the group consisting of L-lactic acid (LLA), trimethyl carbonate (TMC), and glycolic acid (GA), or B is different to A and is lactic-co-glycolic acid (LGA); and wherein the molar ratio of CL to the at least one additional monomer in the copolymer B is in the range between about 1:0.09 to about 1:1. |
